Redirect specific sites to tomcat7 from apache - apache

Question

Before going on, let me say that I'm rather new to application protocols and do not fully understand how this world works ... :-)
This is the situation:
I have several sites being served by apache2.4.7 and those work
well when accessing apache on port 80.
On the other hand, I have only one site being served by tomcat7 and it's
also working well when accessing Tomcat on port 8080.
I tried to redirect traffic from apache on port 80 to that specific site on tomcat on port 8080 and cannot do it (getting a 404 error message).
I have also enabled the proxy and proxy_http modules, but nothing
changed
This is the sites-enabled file for apache:
<VirtualHost 10.10.61.10:80>
ServerAdmin webmaster#localhost
DocumentRoot /var/www
ServerName 10.10.61.10
<Directory />
Options None
AllowOverride None
</Directory>
Alias /racktables /var/www/racktables/wwwroot/
<Directory /var/www/racktables/wwwroot>
Options Indexes FollowSymLinks MultiViews
AllowOverride All
Order allow,deny
allow from all
</Directory>
</VirtualHost>
<VirtualHost 10.10.61.10:80>
ProxyPreserveHost On
ProxyRequests Off
ProxyPass /app1/ http://10.10.61.10:8080/app1/
ProxyPassReverse /app1/ http://10.10.61.10:8080/app1/
</VirtualHost>
All the information that I have read only mentioned that adding the above configuration regarding the proxy* parameters nothing more, nothing less.
However, when looking at the access.log of apache, I get the following:
10.10.61.62 - - [10/Nov/2015:11:32:00 -0300] "GET /app1 HTTP/1.1" 404 410 "-" "Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:42.0) Gecko/20100101 Firefox/42.0"
What is it that I'm missing? Any ideas or hints?
Thanks!

Well, after some digging, the solution was to include everything under the same virtualhost such as this:
<VirtualHost 10.10.61.10:80>
ServerAdmin webmaster#localhost
DocumentRoot /var/www
ServerName 10.10.61.10
<Directory />
Options None
AllowOverride None
</Directory>
Alias /racktables /var/www/racktables/wwwroot/
<Directory /var/www/racktables/wwwroot>
Options Indexes FollowSymLinks MultiViews
AllowOverride All
Order allow,deny
allow from all
</Directory>
ProxyPreserveHost On
ProxyRequests Off
ProxyPass /app1/ http://10.10.61.10:8080/app1/
ProxyPassReverse /app1/ http://10.10.61.10:8080/app1/
</VirtualHost>
